most people that overclock these have gotten them up to 1ghz on a 125mhz fsb, you need to make sure that you pci components will be ok at a 41mhz
pci bus especially the harddrive

The 800 is a different animal, of sorts, being that it runs at 100 FSB default. However, this is still the same core it's 66 FSB bretheren.

This has been called basically a re-badged 533a Celeron II. It just starts out at 100 FSB instead of 66 FSB. This puts them a lot closer to the ceiling, right out of the box. Some have had some good luck with them, but I wouldn't expect as high a percentage overclock from one of these, as say a 566 or 600 C II.

As Phil said, you need some good hardware to run one of these, as you will not get to 133 FSB (the next point at which the PCI bus is back in spec). The further you push it, the further out of spec the bus will be. 125 FSB is a toughie, that most Celerons just can't reach. There are exceptions, and you might get one. Just be ready for head and heart aches from a high PCI bus setting if your cards and hdd can't take it.

What's your mainboard?! Does it have a PCI divider of 1/4 like mine? I got my Celeron 800 up to 131Mhz FSB by increasing the PCI latency from 32 to 64. The 800 has potential cuz I see everyone of these babies doing at least 1Ghz in the CPU database where mine did 1008 at default voltages!

it's not just the same as a 533a though as there was never a 533c cCO chip, as that would have been the best overcloking celeron available due to it's lower multiplyer, unfortunately it's just a shame intel charges so much for a chip that is only as fast a a 600mhz p3, you can pick up 700mhz p3's for less than the price of this and they out perform it without overclocking and when both are overclocked the 700 still out performs it

Hahaha! Face it guys: The Celeron 800 doesn't have anything in common with the 533a. They are the top notch Pentium 3's with a bad cache. Why else would all of them do a Gig out of the box with just 1.75 to 1.85 Vc, huh?! I see a lot of P3 700's only reaching that with a pelt and 1.9 Vc and like 3.7 Vio...

Oh.. Peltier eh?.. hehe.... i dont need no peltier.. just plain home-made air cooling and nothing special to have the P3 cC0s to get a Gig or like mine.. at 1071mhz?? you dont need peltier.

BTW, both Celeries and P3s dont need higher clocked mhz to overclock to a gig.(samething applies to Durons) only if you want to just spend more money for the sound of it.. hehe..
look at my sig..

Like I said: 1.9Vc and 3.8Vio even...

[DocClock aka MadClocker]

Heck, I don't even have v/io options, and I don't need a pelt either. for most newer parts...124mhz bus is just fine...and if it don't boot up, try pulling pci cards, till you find the one/s that are not up to it.
The only way you will know for sure if it will overclock, is to try it..and if you run into trouble..we will be here to help out.
If you read some of the "beginners guides" on the main page...then you have an idea of what you want to start with, and don't worry about asking stupid questions... no question is stupid to someone who dosen't know the answer. After all how's a body to learn?
Good luck with your overclock, and post back with your results....pro or con
